Claude Code leak exposes a Tamagotchi-style ‘pet’ and an always-on agent

Users who have dug into the code claim to have uncovered upcoming features, Anthropic’s instructions for the AI bot, and insight into its ”memory” architecture. Some things spotted by users include a Tamagotchi-like pet that “sits beside your input box and reacts to your coding,” according to a post on Reddit, along with a “KAIROS” feature that could enable an always-on background agent. Users also found a comment from one of Anthropic’s coders, who admits at one point that the “memoization here increases complexity by a lot, and im not sure it really improves performance.”

Not a good day for someone in the release team.
